Link Between Reduction of Suicide Ideation by Esketamine in Add-On and Initial Levels of Psychological Pain and Anhedonia

Brief summary (registry, in English)

This study is looking at how intranasal esketamine (a nasal spray) can help reduce suicidal thoughts in patients with severe depression who are experiencing suicidal thoughts. Suicidal depression is a type of depression where people have active thoughts of suicide, which can be harder to treat with regular antidepressants. In fact, some people continue to have suicidal thoughts even after taking antidepressants. Esketamine has already shown promise in helping reduce suicidal thoughts quickly-often within 24 hours-and these effects can last for up to 25 days. Researchers believe esketamine may work by improving mood-related symptoms like loss of pleasure (called anhedonia) and feelings of hopelessness, which are linked to suicidal thinking. They also think that psychological pain, or emotional distress, might play a role in how well esketamine helps reduce suicidal thoughts. The goal of this study is to better understand how esketamine works to improve suicidal thoughts and whether certain factors (like mood symptoms or emotional pain) can predict which patients will benefit the most from this treatment. This study uses data from two earlier clinical trials, called ASPIRE I (NCT03039192) and ASPIRE II (NCT03097133), that tested intranasal esketamine in patients with depression and suicidal thoughts. All data from these studies are publicly available and can be accessed and analyzed through the YODA (Yale University Open Data Access) platform, a database of clinical trial data that is accessible to external researchers.
